Figure 8. Parasitism rates of planthopper eggs by A. nilaparvatae in the field cage experiments.

(A) Mean numbers of eggs deposited by BPH on rice plants that were infested with BPH only or with both BPH and SSB, and (B) rates of parasitism of BPH eggs by A. nilaparvatae on the differently infested plants. LR tests applied to a GLM were conducted for the number of eggs (Poisson distribution error) and for the percentage of parasitized eggs (binomial distribution error). Data columns marked with asterisks indicate significant differences (**p<0.01) (N = 5).
